Heath is close to the best bodybuilder ever. He is/was superior to Ronnie and Dorian in some places.
But Ronnie and Dorian don't have a golumish torso that didn't scale with the rest of him and ruins ever being considered the greatest.
Will it be surpassed? Not any time soon. You've got to hit the absolute genetic lottery to look like Heath AND not have some flaw that ruins it.
And I reiterate, ruins is only in the context of being considered the greatest. I don't like his physique at all, but you have to give credit where credit is due, he is extraordinary in some aspects.
